MURRAY GIBSON, OF PHILADELPHIA, PENNSYLVANIA;

COMPOSITION FOR THE ORNAMENTATION 0F WALLS AND CEILINGS.

SPECIFICATION forming part, of Letters Patent No. 290,227, datedDecember 15, 1883.

Application filed May 18, 1883. (No specimens.)

To all whom it may concern.-

Be it known that I, MURRAY GIBSON, a citizen of the United States,residing in the city and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Oomposition for theOrnamentation of Walls and Ceilings, of which the following is aspecification.

The object of my invention is the production of an improved plasticcompound which shall be adapted to be applied to a wall, ceiling, orother surface to be decorated, whether such surface be composed ofbrick, concrete, wood, or other material,. either in its natural state,coated with plaster, or faced with canvas or other textile or fibrousfabric, and which, when applied, shall be adherent thereto, and be alsoadapted to set into a rigid mass.

This compound is especially designed to be employed in the practice of amethod of ornamenting walls and ceilings invented by me,

application for patent for which was executed by me under the same dateas thedate of execution of this application.

This compound is especially designed for use in the ornamenting ofeither the interiors or exteriors of dwellings or other buildings,although it is especially designed to be applied to surfacescomposed ofor coated with wood, or to canvas, or other textile surfaces.

The compound is composed of red lead, (commercially known as sugar oflead, and being a preparation of white lead,) whiting, sawdust,linseed-oil, a mastic varnish, and beeswax. The whiting is added to thered lead in order to reduce both the weight and the cost of theresultant compound, and also to add to its bulk. To the mixed red leadand whiting is added sawdust. Fat, linseed-oil,

mastic varnish, and heated or liquid wax are then added to the sawdust,red lead, and whiting, and all the ingredients are thoroughlycomniingled until the mass assumes a pasty consistency.

I do not restrict myself to any specific proportions, but prefer to takethree parts in bulk of red lead, four parts of whiting, and three partsof sawdust, adding sufficient oil, varnish, and wax to render the massof a pasty and coh erentconsistency. The sawdust serves to thicken andrender rough the surface of the mass, and whenthe mixture becomes toothin is to be added in sufficient quantities to effect the requiredthickening, which is a matter dependent upon the skill of the workman,while the liquid elements are to be added to thin the compound in amanner likewise dependent upon the judgment of the workman.

The compound is applicable for the ornamentation of plastered surfaces,but for such surfaces is not as desirable as another compound which Ihave invented, and for which I have executed an application for LettersPatent bearing the same date as this application.

The mass in its, pasty condition is in readiness to be applied to thesurface which is to be ornamented with it according to my method alreadyreferred to.

Having I thus described my invention, I claim A compound for theornamentation of walls, ceilings, and other surfaces, composed of redlead, whiting, sawdust, linseed-oil, copal varnish, and beeswax,substantially as described.

In testimony whereof I have hereunto signed my name this 4th day ofApril, A. D. 1883.

MURRAY GIBSON.

In presence of- JOHN J OLLEY, J r. F. N. DIXON.
